LUBRI CANT.

SPECIFICATION forming part of Letters Patent No. 311,529, dated February 3, 1885.

Application filed September 13, 1884.

T at whom, it may concern:

Be it known that I, HERRMANN RIEDEL, a subject of the Emperor of Germany, residing at the city of Neenah, in the county of Winne bago and State of \Visconsin, have invented a new and useful composition of matter to be used for the lubrication and preservation of the wood and the wood and iron cogs of gearing which is used in the operationof machinery, of which the following is a specification.

My composition consists of the'following in- 4 gredients, combined in or in about the proportions stated-namely: mineral oil, two hundred and fifty pounds; boiled linseed-oil, two hundred and fifty pounds; powdered plumbago, one hundred pounds. These ingredicuts are to be thoroughly mixed together by agitation. The effect of the mineral oil upon the surfaces of the wood or wood and iron cogs which come in contact with each other is to keep them properly lubricated, that of the boiled linseed-oil is to produce a hard and glassy coating upon the wood cogs, and that of the powdered plurnbago is to assist the adhesion of the oils to the surfaces of the cogs, add to their lubricating qualities, and pro duce upon the wood a hard smooth surface of great wearing qualities.

lhe adhesive and cohesive quality of the composition combined as above stated permits its continuous and successful use upon (No specimens.)

the cogs of gearing, it neither forming itself in masses by the rolling motion of the cogs upon each other nor running from them by reason of its too great fluidity, but permits L them to act one upon the other with the consumption of the minimum of power and the production of the least amount of friction and wear of the cogs.

In using the lubricant it should be applied to the cogs in limited quantities and at such times as their speed and required labor demand.

I am aware that some of the ingredients composing this have been used for the same purpose for which this is designed, that plumbago, tallow, and lubricating-oil have long been in use; but I am not aware that all the ingredients of my composition have been used in the proportions above named.

That I claim, and desire to secure by Lettors Patent, is

The herein-described composition of matten to be used as a lubricant, consisting of mineral oil boiled linseed-oil, and powdered plumbago, in or in about the proportions specified.

HERRMANN RIEDEL.
